Dear Reader

We are invisible to each other

A happier thing for you than for me

I suspect; these words are from another

For you alone, and everyone to see

But not all locks are made in the same way

Nor are all keys forged from the same alloy

Somehow, the two must meet and then sashay

The better to their compound spell deploy

Note that loosing and binding both await:

Egress and entrance lurk in every gate

An inky outline of ideas’ weight

For you, forensically, to contemplate

The door unlocks, the scene is yours to read

All see the marks, but your sleuth’s eye they need
